The taxonomy in relations to the PacificGecarcinus quadratus is disputed, with many considering it and G. lateralis to be conspecific. Another closely related species, Gecarcinus ruricola, occurs together with G. lateralis in the tropical western Atlantic, but its carapace is typically almost entirely blackish, dark maroon, purplish or yellowish.
Description
As suggested by the name blackback land crab, it has a large blackish spot, which, although the exact shape is variable, covers a large part of the central carapace ("back"). The legs, claws and outer sections of the carapace are reddish, orange or whitish. The carapace may reach a width of up to Шаблон:Convert.
Ecology
G. lateralis occurs along the dry zone of sandy beaches and nearby hills, around Шаблон:Convert above the highest high tide mark, where there is no standing water, but significant interstitial moisture.[1] They need to return to the ocean to breed (the larvae are released into the sea).[2] Furthermore, its gills need to be moist all the time, or it will die. Compared to most other crustaceans, its blood also has a higher oxygen carrying capacity.[2][3] It is largely herbivorous, but will take animal matter if available.
